ALTHEIMER (AP) — Jefferson County authorities say a 23-year-old man was shot and killed during an argument with his girlfriend’s grandfather.

Authorities say deputies responding to reports of a domestic dispute Thursday morning at a home in Altheimer found 23-year-old Tabius Love dead at the scene.

Sheriff’s Major Lafayette Woods Jr. says Love lived at the home with his girlfriend and her grandparents and that Love and the grandfather apparently argued before the shooting. Woods says the grandfather was arrested for probable cause for first-degree murder — but has not been formally charged.
